As model system we choose Rayleigh-Bénard (RB) convection which is the paradigm of thermally driven turbulence (see the reviews of [1]}, [2]}, [3]}, [4]}), where a fluid between two parallel plates is heated from below and cooled from above. In previous studies, the effect of various plate properties on the flow structure and the heat transport were examined, e.g., staggered conducting and insulating strips on the plate [5]}, [6]}, temporally-modulated temperature [7]}, [8]}, plate with roughness [9]}, [10]}, [11]}, and plates with different wettabilities [12]}. Here we pick RB convection as model system to study the effects of attaching bubbles on the global heat or mass transport in buoyancy-driven turbulence.
